* Adds non-static final field printing for `Instance`s
* Adds specialized printing for `Closure`s (tearoffs).
* Instances of `Mint` and `Type` can also appear in constant
pools, so handle both in ObjectToSExp.
* DartValueToSExp is a wrapper method for ObjectToSExp that
also checks to see if the value is defined in the constant
pool. If it is, the object is serialized as a reference to
that definition.
* Reworks the `tmp_*_` fields used for non-reentrant cases
to be per function to make it easier to understand how they
interact. (Only cross-function tmp field that remains is
`tmp_string_`, since its contents are always immediately
converted to a C string and then no longer needed.)

Previously, KernelIsolate::CompileExpressionToKernel was called
with is_static == false and klass == nullptr, which doesn't make sense:
this call requested to compile expression inside instance method context but
without enclosing class. This results in a malformed kernel AST and crash
in bytecode generator.
Fixes vm/cc/LinkedHashMap and vm/cc/Service_* tests in bytecode mode.

After landing d3f3b46, which adds support for vm-service to the run_vm_tests binary,
random vm/cc tests started to time out. The VM shutdown procedure waits
for the service isolate to shut down, which it doesn't do.
Since we haven't been running the vm-service isolate before, this
might've been an existing issue which is just surfaced now. This CL
disabled starting vm-service (like it was before) except for the
particular test which needs it.

This way, users of S-expression deserialization will not also pull in
the rest of the upcoming IL deserialization functionality (and
anything extra needed by that).
Also changes SExpParser::ReportError to just print the error
information to stderr and abort, instead of using the Dart VM
exception machinery.

This reverts commit d6e9e15cf1.
Reason for revert: The recognized kind was likely intentionally
carried over to the DIF, since the inliner doesn't distinguish
between dynamic and non-dynamic call sites for these recognized
method replacements. In addition, the replacements are speculative
and can't handle arbitrary inputs, so deoptimization should end up
re-executing the original DIF call and thus cause an appropriate
type error to be emitted via the DIF.
Original change's description:
> [vm] Clear recognized method info on dynamic invocation forwarders.
>
> Similar change to b68e5c4338, where this information gets copied
> over into the new dynamic invocation forwarder from the original
> function.

This is the beginning of allowing us to - wherever we process kernel
data - make decisions based on the kernel version. Said another way,
we can actually start to change the kernel format without breaking
backwards compatibility in the VM.

AST-based flow graph builder has a heuristic logic on when to generate
DebugStepCheck when assigning value to a variable. This logic depends on
right-hand side expression. In order to replicate the same behavior
with bytecode, bytecode generator would also implement this logic and
generate explicit DebugCheck instructions instead of stopping on every
StoreLocal/PopLocal/StoreContextVar.

* Add a new `SExpDouble` atom and change `SExpNumber` to `SExpInteger`.
* Allow for negative integers in deserialization.
* Add support for `LocalVariable`s and related instructions.
* Function objects are now represented by actual S-expressions generated
with the new `FunctionToSExp` method. Previously, they were only represented
by a symbol containing their canonical name.
* The top-level tag for a serialized flow graph is now `FlowGraph`, not
`function`. This avoids confusion between serialized flow graphs and
serialized function references. Similarly, the old `FunctionToSExp`
method is now called `FlowGraphToSExp`.
* Made all SExpression* returning functions that take Object (or subclass)
instances return nullptr if the passed in instance is the null object,
except for ObjectToSExp, which returns the symbol `null`.
* Factored out creating tags for the different kind of block/function
entry and also created an `Entries` section to the top-level `FlowGraph`
form that contains function entry points similar to the `Constants` one
instead of inlining entries as separate elements in the `FlowGraph` form.
* Additional extra information in verbose mode for some elements.
